I guess you don't do the sources then.

Mirroring both binary-all and binary-i386 is no problem, is it?  You
now have everything that's in binary-all in binary-i386 anyway.  The
symlinks to slink might be more of a problem.  What are you going to
do when you decide you want to mirror woody?

In the (unlikely) case you want to add an architecture to your mirror
you might want to consider mirroring both binary-all and binary-i386.
If your mirroring tool (or proxy!) flattens symlinks for you (even if
you really don't want it to), first do binary-all, then create links
for each architecture to binary-all and finally mirror architectures
you want.  The links are easily created with perl like so (please be
nice, it's my first perl program :-):

  #! /usr/bin/perl

  my($source,$target) = @ARGV;

  # Duplicates the directory tree starting at $source as $target and
  # populates $target with symbolic links to all files in the $source
  # tree.  This results in a symlink mirror of the $source in $target.

  sub treelink {
      my($source,$target) = @_;
      (-d $target) || mkdir($target,0755);
      $source = "../$source";
      foreach $base (<$source/*>) {
          $base =~ s,.*/,,;
          if (-d "$source/$base") {
          } else {

I just wished my http and ftp proxies didn't insist on pretty printing
directory listings.  All info about symlinks are gone, plus sizes are
in kb and times in hh:mm:ss.  Apart from all the html yuck, that is!
This wrecks havoc with just about any mirroring tool I've looked at.
